MAKING ART IN BED

"So take a shower, read a good book, then go to sleep. And do it now!"
A friend emailed me this advise a couple of nights ago when I told her that I was going to bed with a stack of papers that I had let pile up for toooo long.  Who knows what might be in that stack  -  bills to pay, checks to cash (YES!)
So under what category does making art fall?  Is it work or is it equivalent to reading a good book? 
This is a small mono-type with colored pencil.I inked the "plate" ( a piece of plastic), let it dry over night, and then printed it on a damp piece was 90lb hot press watercolor paper.
I love doing these  -  so I guess it falls under the category of reading a good book.
